Method and system for communicating user interfaces between first and second users over a network

A machine-readable medium storing a sequence of instructions that, when executed by a machine that includes at least one processor, causes the machine to:

• generate a first user interface that includes a first plurality of items and a first plurality of selection functions, the first plurality of items respectively associated with the first plurality of selection functions;
• present the user interface to a first user over a communications network;
• receive a first plurality of selections from the first user that identifies a second plurality of items, the second plurality of items having been selected from the first plurality of items by the first user using the first plurality of selection functions;
• generate a second user interface that includes the second plurality of items and a second plurality of selection functions, the second plurality of items respectively associated with the second plurality of selection functions;
• present the second user interface to the second user;
• receive a plurality of selections from the second user of a third plurality of items, the third plurality of items having been selected from the second plurality of items by the second user using the second plurality of selection functions;
• generate a third user interface that includes the third plurality of items and a third plurality of selection functions, the third plurality of items respectively associated with the third plurality of selection functions;
• and
• present the third user interface to the first user.
